How do I sync two tracks?

[MysticalChicken]

I was playing around with the vocal remover and finally managed to completely (or at least, almost completely) remove the vocals from The Decemberists' "Sons and Daughters" (along with two of their other songs). I exported the vocal-less track and, long story short, recorded myself singing along with it. But when I import both the vocal-less song and my vocals, I'm about one second ahead (maybe a little less) of where the vocals are actually supposed to go. How do I sync them up?

EDIT: Never mind, I think I figured it out. Time shift tool. Durrrr.

EDIT again: Okay, that worked. Except not, because I couldn't hear myself--either I don't sing loudly enough, or the mic I'm using sucks. Must re-record.

There's a volume slider on the left side of the track that will help make the levels match.
